The matchup, announced Monday by promoter Sustain, will be part of
the main card of “VTJ
4th,” which takes place Feb. 23 at Ota City General Gymnasium
in Tokyo.

Uno fought and won three times in 2013, a feat the 38-year old had
not managed since 2006. The onetime UFC lightweight title contender
is 4-3 since dropping to featherweight in 2010. His opponent,
Idaho’s Brock, moves up from bantamweight for the bout. A training
partner of Scott
Jorgensen, Brock has won six of his last eight, including his
most recent bout under the Bellator banner in October.
